Opal, I've never thought about whether you are married or otherwise would affect your credibility in whatever you posted. Sometimes I do think you have a tendency to overanalyse human relationships. But since your friends all felt your suggestions were good, then I guess your methods work for them. Perhaps you haven't encountered a relationship where you entirely do not have to think about how to maintain a relationship. Then I must say I'm really blessed. Interestingly, I told my hubby about our thread and asked him if he feels he's been consciously putting effort to maintain our marriage or relationship. He laughed saying jokingly, "of course not lah, aiya no need to do so much for you one lah..." I feel touched after hearing such a response because to me, he's done a lot for me...yet he could jokingly tell me that he doesn't have to do much for me. As how I've understood him, we're of the same wavelength and that is no need for a conscious effort to maintain what relationship. We're doing well naturally as a married couple and that's what matters. This is something I've never experienced with any other men I had been with. Also, in case you need another answer from a man, when I told him about the thread on "What keeps a man faithful", he laughed out loud and said, if a man wants to be unfaithful, he would be unfaithful, no other reason or factors. Then he started joking about that's a good idea and I started tickling him. This is basically how we communicate with one another...really nothing to fuss or think deeply about. My experience with him feels new every day without efforts at all.
Anyway to lostbabe, now that you've answered the questions, I believe you realise you would be happier without him. You just need the courage to seek for your own happiness. I can't provide exact details on how you should do it but I don't suggest using divorce to threaten him to see if he's hurt - no point. If you really made up your mind to divorce, then just be firm. Never use it as a threat or tool to dig out whatever truths you want to hear. Hope you would make a wise decision for your own life. If you analyse the whole situation at a deeper level, your kids may not be the ones who suffered from a failed marriage. In fact you and your kids could benefit from it and start anew. Just offering another perspective for your consideration.
